OAV Air Bearings FAQ News

OAV Air Bearing Bar , It is a complete offering of Air Bearing Bar produced with profile design for easy retrofitting into existing applications or designing into new applications.

OAV air bearing bar generates evenly distributed gas film between surface and the substrate, because of low gas viscosity, friction losses by viscous shearing therefore, any mechanical contact is avoided.

Combination of air pressure and vacuum OAV air bearing bar hold substrate down while simultaneously lifting from surface for ultimite precision and fly hight. Fly height range of 20 to 120 microns at stability of ±5 microns.

OAV has updated the Product Book with new features to help educate the engineers help to design and assemble the OAV Air Bearings. In addition to the list of products, more information including instructions and easy-to-understand diagrams can be found regarding design and installation of air bearings.

By popular demand, High Speed Face Collars were added to the standard product line. High Speed Face Collars are used in conjunction with Thrust Air Bearings and differ from the standard Face Collars with a more sophisticated and balanced design. This allows the air bearing system to spin with ultra precision and drastically reduced vibrations making the High Speed face Collars ideal for ultra precision measurements and high rotational speeds.
